The Binding Energies of Atoms on Amorphous Silicate Dust: A Computational Study
Kristoffer Hansson, W. M. C. Sameera, Clarke J. Esmerian +6
Context. We investigate the binding energies of atoms to interstellar dust particles, which play a key role in their growth and evolution, as well as for the chemical reactions on…

Chemical pathways of SO2 with hydrogen atoms on interstellar ice analogues
Thanh Nguyen, Yasuhiro Oba, W. M. C. Sameera +2
Sulfur dioxide (SO2) is a sulfur-containing molecule expected to exist as a solid in the interstellar medium (ISM). In this study, we performed laboratory experiments and computati…

Determination of the branching ratio of CHOH + OH reaction on water ice surface at 10 K
Atsuki Ishibashi, Hiroshi Hidaka, W. M. C. Sameera +2
The CHO and CHOH radicals can be important precursors of complex organic molecules (COMs) in interstellar dust. The COMs presumably originating from these radicals were abu…
